Verification of truth table of BCD to Decimal converter using 74HC42 ICs. Apparatus Required Digital Circuit Lab Kits with 74hc42 ICs, Strand wires, seven segment display Theory Most often seven-segment displays are used to display the digits in digital watches, calculators, clocks, measuring instruments and digital counters, etc, Generally, LCD and LED segments provide the display output of numerical numbers and characters. However to display the characters and numbers (in order to produce the decimal readout), seven-segment displays are most commonly used. Mostly these displays are driven by the output stages of digital ICs such as latches and decade counters, etc. But these outputs are in the form of 4-bit binary coded decimal (BCD), and not suitable for directly driving the seven-segment displays. D A display decoder is used to convert a BCD or a binary code into a 7 segment code. Create the truth table describing the function of a BCD to seven-segment decoder. The lower case letters, d0-d9, represent the segments on the display while the upper case letters A-D represent the BCD input.
